I believe that the 12V source will try to charge the 6V source, overcharging the 6V battery if a diode is not present. From: Bob McCallum Sent: Wednesday, April 09, 2014 3:37 PM Subject: RE: AeroElectric-List: Re: When are diodes needed? Yes. All else being equal if you connect both a 12V and a 6V source in parallel to a single load without any other intervening components then the 12V source will supply the load and the 6V source will sit idly by doing nothing.

Yes absolutely ! (assuming the sources are batteries. If they are diode iso lated power supplies (alternators) the original statement stands) I wasn't suggesting that this was a practical thing to do. Mearly that the higher voltage source will supply the load. Normally we would be talking pa ralleled batteries or a battery and an alternator. In either case the highe r voltage source will supply the load. All else being equal=2C the lower vo ltage source will be idle until the system voltage sags to equal the lower. (even this is an oversimplification=2C but hopefully gets the idea across. The higher of two paralleled differing voltages will be supplying the load s=2C including attempting to raise the lower voltage source. That's the bas is of how a charging system works) Bob McC From: wschertz@comcast.net Subject: Re: AeroElectric-List: Re: When are diodes needed? =0A =0A =0A =0A =0A =0A I believe that the 12V source will try to charge the 6V source=2C =0A overcharging the 6V battery if a diode is not present.=0A =0A =0A =0A =0A From: Bob McCallum =0A Sent: Wednesday=2C April 09=2C 2014 3:37 PM=0A =0A Subject: RE: AeroElectric-List: Re: When are diodes =0A needed?=0A =0A =0A Yes.
